A little history is in order .. Some of my earliest memories are of
tinkering with electronics:
#6 ignition batteries, door bells,
electromagnets, Mr. Wizard, Boy Scout manuals, pinball machine parts,
anything that did something when power was applied :-)

But one of the coolest projects ever was that of making my own radios,
winding coils, shellacing wood orange-crate board bases, etc.

Now that I've taken a break from my recent musical endeavors, I've
returned to some of these cherished projects.
